A certain flight arrives on time 89 percent of the time. Suppose 200 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that ​(a) exactly 165 flights are on time. ​(b) at least 165 flights are on time. ​(c) fewer than 187 flights are on time. ​(d) between 187 and 192​, inclusive are on time.
